Vairable Question

Hello

I have a function and its called delete. When i delete my file it deletes it from two places, image/cache and another the saved cached image displays like a&t_logo-100x100.jpg 100x100 means width and height.

currently on this line $cached_image = FCPATH . 'image/cache/' . utf8_substr($path, 0, utf8_strrpos($path, '.')) . '-' . 100 . 'x' . 100 . '.' . $extension;

I have to enter the width and height manually.

I would like to be able to do this $width & $height replacing the manually entered width and height.

$cached_image = FCPATH . 'image/cache/' . utf8_substr($path, 0, utf8_strrpos($path, '.')) . '-' . $width . 'x' . $height . '.' . $extension;

How can I make it so when I enter in $width & $height variables that it would pick width and height up automatic.

utf8 is a custom helper that's autoloaded

PHP Code:

<?php

class File extends MX_Controller {
    public function delete() {
        $json = array();

        if (!$json) {
            $path_post = $this->input->post('path');
            if (isset($path_post)) {
                foreach ($path_post as $path) {
                    
                    unlink(FCPATH . '/image/' . $path);
                    
                    rmdir(FCPATH . '/image/' . $path);
                    
                    $extension = pathinfo($path, PATHINFO_EXTENSION);

                    //$cached_image = FCPATH . 'image/cache/' . utf8_substr($path, 0, utf8_strrpos($path, '.')) . '-' . $width . 'x' . $height . '.' . $extension;
                    
                    $cached_image = FCPATH . 'image/cache/' . utf8_substr($path, 0, utf8_strrpos($path, '.')) . '-' . 100 . 'x' . 100 . '.' . $extension;    
    
                    unlink($cached_image);
                }
            }

            foreach ($path_post as $path) {
                $json['success'] = $this->lang->line('text_delete');
            }
        }

        $this->output->set_content_type('Content-Type: application/json');
        $this->output->set_output(json_encode($json));
    }
} 


In stead of having the width and height in image name should I just have it normal a&t_logo.jpg That I can do what would your thoughts be on that?

There's only one rule - please don't tell anyone to go and read the manual.  Sometimes the manual just SUCKS!
